That is ksh88. That is going to be a bit complicated with dd and terminal settings and such. Does it need to be ksh, or could you use bash?
*edit* never mind ... input is a text file..

try awk with -F"", it should give you every single character approachable.

Try something like:
Code:
while read line
do 
  while [ -n "$line" ]
  do
    newln=${line#?}
    ch=${line%$newln}
    line=$newln
    echo "$ch"
  done
done < infile

or feed itkamaraj's command into a while loop...

Thanks
